Matt Bomer wears a Kelek Tenor Dorly

In Shane Black's The Nice Guys, set in a smoggy 1977 Los Angeles, Matt Bomer plays John Boy, the calm professional the conspiracy hires when it wants the job done cleanly. He is the scariest man in a film full of bunglers, and he dresses the part: dark suit, black leather gloves, cufflinks set with a blue stone.

Frames from the film catch the watch on his wrist, pistol up, riding above the glove on a fine steel bracelet. The case is rectangular and bright, the dial pale, with what look like chronograph pushers on the flank. The shape and the period point to the Kelek Tenor Dorly 1376, a jump hour automatic chronograph from around 1975. That watch is a genuine oddity. Tenor-Dorly built the automatic jump hour base, Dubois-Dépraz added a chronograph module, and Kelek finished it, and the result was reckoned the smallest automatic chronograph of its day. The 'TDBK' caliber name even spelled out the partners. It landed just as the quartz crisis closed in, and Tenor-Dorly went under in 1975, part of why these are scarce now.

The one thing the frames still will not give up is the dial face, where a jumping hour window in place of normal hands would clinch it. The rectangular case and the pushers fit, so this sits at likely rather than nailed down. Read the dial off a cleaner frame, or own the watch? The comments are open.
